TRAc'ron. i

T0 all witam t may concern: i

Be it known that I, LLOYDL. BRODER, a citizen of the United States of America, and resident of Eugene, in the county of Lane and State of Oregon, have invented certain new and useful lmprovements in Tractors, of whichv the following is a specification.

T his invention relates to tractor's and particularly to tractors designed for use in Specification of Letters Patent.

wherein like characters denote correspondmg which- V 'rorica i parts Vin the several views, and in vFatennted Mar. 1, 1921.' Application filed August 5, 1919. serial Naeinec..

Figure 1 illustrates a view in elevation of i v tractor embodying the invention; V

Fig. 2 illustrates a plan view thereof; In theseV drawings 010 denotes a frame which is substantially rectangular in plan 'fiexcept that the front ends of the .frame farming as for Operating cultivators, potato v diggers and other farminachinery, the said 'invention having for its object the provision of novel means whereby the traction wheel or bull wheel will operate or run in a furrow f formed by the plow. Furthermore, an object of this invention is to provide novel means'whereby the blades (which term will hereafter be used to denote the plow shovels or other implements which are designed .for cultivating or Cutting) and their attachments .maybe elevated or lowered by simple mechanism and furthermore, whereby the depth of operationof the points' of the blades maybe a'djusted with relation to other parts thereof. w

`Furthermore, an object of this 'invention is to provide novel means whereby the draft or position of the frame "of theapparatus may be changed transversely of the axle while providmg means for Vsteering the mechanism. i i

A still further object of'this invention is to provide a frame having transverse oscili i latory motion with respect to thel front aXle.

thus allowing movement which will compen- 'sate for unevenness of the surface over i which the tractor is vpas'sing and permitting raising or lowering ofthe wheel on either side of the frame without materially inter-` fering With theposition of the blades.

A still further object of the invention is to provide a tractor having a wheel provided with means whereby soil deposits maybe readily dislodged while the said wheel is rotating.

Vith the foregoing and other objects in view, the invention consists in the details of construction and in the arrangement and combinationof parts to be hereinafter more fully set forth and claimed. V

In describing the invention in detail, reference will be had to the accompanying drawings forming part of this specification :converge slightly and at their forward ends the said frames have downwardly projecting extremities 11s forming an anchorage to which the flanges 12 and 13 of plates 14; and

15 respectively areseeured. Thesaid plates are secured 'to a head 16 which is held in .place by a guide 17 and the said head ha'sfa pivot bolt 19 extending through it, the said pivot bolt extending'through a member20 andwith relation to which theframe oscil lates transversely. e

The front axle comprlses two separated bars 21 and 22 with relation to which vthe frame is slidablev and the.v bar` 21 has a series of apertures 23 so thatv the frame in whicha shaft 25 is rotatable, the low'erlv end of said shaft having an arm'26`project-w ing therefrom, and connected to .thest'eering l rod 27 by fastenings such as 28. Thesteeringlrodf has a series'of apertures 29 so vthat the steering rod can be`` secured atdifferent either to the right orv left hand side of the center for the purpose of steering the front in dotted linesv in 2.' w

` The upper end of theshaft 25 has a gear wheel 30 which engages with the gear wheel p .w

31 of the steering shaft 82 and the steering shaft has an Operating wheel 83-which may be within convenient reach of an operator.

The rear section of the steering shaft is journaled in a bearing 34 on the standard 85.

A crank 36 is journaled in the sides offthe.

frame and a crank 87 has itsends journaled in segmental racks 88 and 39` which racks.V

positions of yadjustment7 as shown in Fig. 2,` a

truck of. the tracton'all of which isfshownj f are. slidable in guides 40 land 40'l respec- "tively, carried by the sidesof the frames 'preferably in front of the crank 36. i

A shaftl is journaled in standardsif2 and 43 secured 'to the frame and thesaid shaft has a pinion 4A meshing With the rack 38 and a pinion 45 meshing With the teeth of the rack 39, so 'that as the shaft tl is vrotated, andV according to the direction of rotation, 'the segmental racks are elevated or lowered as shown in dotted lines, Fig. 1.

As a means for rota'ting` the shaft 41, a Worm Wheel 46 is mounted on the said shaft and the said Worm Wheel is engaged by a worm 47 on the shaft 48; The forward end of the shaft 48 is journaled in a bearingv49 on 'the standard 43 and the, rearportion of saidV shaft 48 is journaled in a bearing 50, said shaft being provided With an Operating Wheel' 51 by which. the shaft is turned for the purpose of adjusting the segmental racks i and ,the heightof the pivoits of the Crank 37.

i the frame.

The Crank-s '36 and37 constitu'te supports ,gn-connections for a plow beam 60, the' forwardend of the said ploW beam having a clip 61bol'ted tov it, the said clip embracing thecrank 37. The plow beam near its rear end has a clip 62. a'tta-ched to i't, which' clip couple's jthe crank. 36fto the said beam so that as the cranks are rotated, they raise or lower the beam according to the direction of rota'tion of the said cranks.

The heig'hlt of the plow beam at the for- `lWard-.end vis controlled' by means of the toothed segments lheretofore `described so vthat by 'this adjustment, the front or points of the'plow sho'velsor shares vmay be til'ted to insure their proper operation.

Aymotor 68 of any appropriate type may 'be mounted on the frame andjthe drive shaft 6-l 'thereof may have a gear Wheel 65 meshi ingp'with agear Wheel 66 on the shaft67,

quadrant 59 which is also secured to.

which' shaft 6,7 is journaled in bearings 68.

The transmission 69 is of standard type.

N ear the rear end of the shaft 67 the worm 70 is mountedl and the said Worm meshes with a Worm Wheel 71 on the rear aXle 72 which aXle is journaled in bearings 78 and '74 attached to the sides of the frame. The

rear axle or shaft has a traction or bull wheel-75 and the face of the said Wheel has said grooves alternately tapering to opposite sides of edges of said Wheel and "this provision insures greater traction and prevents i'ouling for the reason that deposits are caused to dislodge or Work out on the sides of the Wheel.

The bearing' .'30 and thestandard 35Vare secured on to a sub frame 77 rising from the frame 10 and are supported thereon.

It isto be understood of .course that learth working' elements of different types may 'be lVfshaped grooves 76 between the lugs, the

suspended from the 'cranks, that is to-.say,

they may comprise the ordinary gang plow or cul'tlvator or harrow, vand the lnventor 'does not wish to be limited with respect to these features. i I i As a description of thefunctions ofthe elements has been given and the relation of the elements to one another .has been stated in connection With |the descriptions. of the 'elements themselves, a resum of the operations or functions of the device is :belleved 1 unnecessary to ,an understanding .of the ini vention by those skilled in l the ar't.

I claim-- i Tn tractor; a frame, guides thereon, racks slidabie therein, toothed Whee1s`en0fagingthe teeth of the'se'menfts; means f 0rrotatably supporting` the toothed Wheels in operativeyrelaton,to the segments, means for rotating the Wheels, a beam support journaled in the V too'thed segmei'l'ts,V means Vfor connectinp; the beam support to abeam, a second beam support J-ournaled 1n 'the.-frame, means for conneotlng the said seco'ndbeam support to the beam, means forrotatingthe iast mentionedbeam support, and means for communicating the motion of one beam support to the other beam support.
